Though luminiferous ether is a term hardly used now days, it is valid in respect to the propagation of starlight falling earth side, since the only other alternatives are a vacuum, which does not support the aberration of starlight, or a space-time continuum, which supports only mathematical prediction sans any ontological basis.  Since this entire thesis is based upon field theory, rather than particle theory, the investigation of field behavior, particularly in light of classical physics prior to the advent of the more abstract relativistic space-time continuum, is long overdue.

In this experiment, two spinning masses on the ends of a lightweight beam (e) are evaluated in terms of a grazing beam of light, to see if their motion affects the field, by determining if there is any change between this grazing beam and the source beam.

Ideally, a coherent and highly collimated beam source at (b) is split into two beams by a beam splitter (c), and set in two directions:  one bypassing the entire assembly, thus serving as a reference, and the other caused to follow a square recirculation path just outside the spinning masses, by four (f and g) front surface mirrors stationed at the corners of a square.  Not only should the beam be highly collimated, it should as well be very narrow, so that it can circulate as many times as possible around the four mirrors, eventually escaping at the top of mirror (g).  The beam can enter this pathway at any of the corner mirrors, and is shown entering underneath mirror (g).

Mirrors (d) are front surface mirrors which can be stationed so that the rejoining of the two separated beams at the final beam splitter (c) just before screen (j), is collinear on its last leg as it reaches the rear projection screen.

Beam (h) is a residual exit beam not used in this evaluation.

Base (a) should be a heavy platform free from any vibrations which might be caused by the rotating mass assembly connected to an electric motor from either above or below this platform.

This assembly in part, or all, should be housed inside a vacuum chamber.  Such a chamber can be made up from 1/2" Lexan plates.

You may choose to have the motor inside or outside the assembly, as dependent upon your design logistics and pragmatic limitations.
